Jim:
We planted extensive haemanthus hardiness trials last year. So far, the
only species that is up is H. montanus. Our winter only dropped to 12
degrees F. last winter. Most are not up at this time, but are fine
including H. humilis ssp. hirsutus. H. albiflos was a loss in all
locations ad was H. deformis. I will know more as they continue to
resprout..hopefully.
